The GCP project ID is auto-configured from the GOOGLE_CLOUD_PROJECT environment variable.
You will need a topic and a subscription to send and receive messages from Google Cloud PubSub. You can create them in the https://console.cloud.google.com/cloudpubsub or use the gcloud example below.
gcloud projects create gdg-bristol-pubsub-poc-1 --name="PubSub POC" --organization=[TODO] --folder=[TODO] --labels=gdg=bristol --set-as-default
gcloud info
export GOOGLE_CLOUD_PROJECT=`gcloud config list --format 'value(core.project)'`
gcloud services list
gcloud services enable appengine.googleapis.com pubsub.googleapis.com stackdriver.googleapis.com logging.googleapis.com
gcloud services enable storage-api.googleapis.com chat.googleapis.com
gcloud services list --enabled
gcloud pubsub topics create testTopic
gcloud pubsub subscriptions create testSubscription --topic testTopic
gcloud pubsub topics publish testTopic --message "Testing messaging"
gcloud pubsub subscriptions delete testSubscription
gcloud pubsub topics delete testTopic
Your application must be authenticated via the GOOGLE_APPLICATION_CREDENTIALS environment variable.
If you have the Google Cloud SDK installed and access to a web browser, you can log in with your user account using the gcloud auth command.

The standard Spring Boot actuator is enabled for this demonstration.

If there is time we can show how Spring Boot integrates with Prometheus, ZipKin and Grafana.
